Was wondering if anyone had an app or service they use to send out texts to players registered for a particular tournament? What I am looking to do is the following:

- Player registers for a tournament
- Player has option to sign up for text alerts.
- TD does not have to manage a zillion different numbers. Just sends a message that gets broadcast to everyone who has signed up for the alerts.
- TD has the option to use the SMS alerts for 2 minute warning - but the official 2 minute warning still comes from a horn.
- TD can use the SMS to notify players when the 2nd round is starting.

(etc etc etc)

- Players can unsubscribe on their own at any time.

Thoughts? I have to believe this would be especially useful where there are players who do not use any social media whatsoever to stay in touch with them. There's a rather large contingent of players near where I live that have nothing to do with social media at all and the only way they communicate is via text or call.
